Activity: Myth-Buster Poster
Assign students to groups of 3. Each group chooses ONE myth to debunk. The goal is to create a "Did You Know?" poster designed for a school hallway that turns the "fake news" of the past into historical fact.
The Hook
A catchy "Myth" statement that people usually believe.
The Debunk
The specific historical evidence from the video.
The Visual
An illustration (fireworks, a scroll, a clock) to draw attention.
Guiding Questions for Discussion
Why do we celebrate the 4th instead of the 2nd? (Historical memory vs. technical legal dates).
Does the "technical accuracy" of the date change the meaning of the holiday?
Why did it take until 1938 to make it a paid holiday? (Connection to government growth and labor laws).

INDEPENDENCE DAY EDITION
Myth
"Independence was declared on July 4th!"
Reality
Congress officially approved the Lee Resolution to separate from Great Britain on July 2nd, 1776 . July 4th was simply when the text of the Declaration was approved.
Myth
"Everyone signed the document on July 4th."
Reality
The "fancy parchment" wasn't ready for signatures until July 19th . Most of the delegates didn't put pen to paper until August 2nd, 1776 .
Myth
"It has always been a paid federal holiday."
Reality
Congress didn't make it a federal holiday until 1870 (unpaid), and it didn't become a paid day off until 1938 —over 160 years after independence!
